How do I set the Settings property in XmlTextWriter, so that I can write each XML attribute on its own line?
Use the static Create() method of XmlWriter.
XmlWriter.Create(filePath, settings);Note that you can set the NewLineOnAttributes property in the settings.
I know the question is old, anyway it's actually possible to set indentation for the XMLTextWriter. Unlike with the XMLwriter, you don't have to pass through the settings; you should use the Formatting property:
XmlTextWriter writer = new XmlTextWriter(filePath, Encoding.UTF8);w.Formatting = Formatting.Indented; Seehttps://msdn.microsoft.com/en-us/library/system.xml.xmltextwriter.formatting(v=vs.110).aspx
